Features
• Wide operational supply voltage range (VCC = 6 to 40 V)
• Various control signals are generated when microcomputer system runaway occurs. (NMI signal and STBY signal
are generated by detecting voltage level, and RES signal is generated by monitoring the time after NMI signal is
detected)
• Regulated voltage, NMI detecting voltage, STBY detecting voltage are adjustable.
• At low voltage and re-start, the delay time of RES signal is adjustable
• Watchdog timer filtering uses the minimum clock input pulse width and maximum cycle detection method

If the voltage of VOUT pin declines to less than Detection voltage(1) (because of an

If the voltage of VOUT pin inclines to more than Detection voltage(1) (in case of restart from LVI state), NMI signals are stop. tr ≈ 0.5•Rf•CRES(sec) has passed since
then, RES signals are stop. Connect capacitor CRES between this pin and GND to

The system contains the power-on reset function required when a microcomputer is turned on.
The reset period may be set with external components RR and CR. Equation 2 specifies how to determine the reset

Watchdog Timer Function
The system contains a bandpass filter for pulse width detection, which outputs a reset pulse when input pulses are not at
the preselected frequency (at either a higher or lower frequency).
The RC characteristic of the bandpass filter may be set with external components Rf and Cf. Equation 3 specifies how
to determine the minimum pulse width (tmin) for runaway detection of the bandpass filter, and figure 4 shows the
characteristic of the filter.

Low Voltage Monitoring Function
The system contains a circuit to send a control signal to the microcomputer when the output voltage drops. The circuit
includes the following features.
• Two-point monitoring of output voltage (VNMI and VSTBY)
• Availability of fine adjustment of Vth1 (VNMI) and Vth2 (VSTBY)
• Output of control signal in standby mode of microcomputer
Figure 5 shows the timing chart of control signals when the output voltage drops.
If the output voltage drops below Vth1 (4.60 V), the NMI signal rises to request the microcomputer to issue the NMI
interrupt signal. The RES signal falls tRES seconds after the NMI signal rises. If the output voltage drops further to
below Vth2 (3.2 V), the STBY signal rises to enable the micro-computer to enter standby mode.

Notes: 1. Value under Ta ≤ 77°C. If Ta is greater, 8.3 mW/°C derating occurs.
2. Allowable temperature of IC junction part, Tj (max), is as shown below.
Tj (max) = θj–a•Pc (max)+Ta
(θj-a is thermal resistance value during mounting, and Pc (max) is the maximum value of IC power
dissipation.)
Therefore, to keep Tj (max) ≤ 125°C, wiring density and board material must be selected according to the
board thermal conductivity ratio shown below.
Be careful that the value of Pc (max) does not exceed that PT.

Precautions
If the IC’s ground potential varies suddenly by several volts due to wiring impedance (see figure 6), a false RES pulse
may be output. The reason for this is that potentials in the RES pulse generating circuit change together with the VOUTGND potential. The reference potential of the comparator in figure 7 and the potential of the external capacitor have
different impedances as seen from the comparator, causing a momentary inversion. The solution is to stabilize the
ground potential. Two ways of stabilizing the IC’s ground line are:
• Separate the IC’s ground line from highcurrent ground lines.
• Increase the capacitance (Co) used to smooth the VOUT output.
